Looking for a rack to fit a bmw z4 coupe.

 Any reccomendations?

Tow ball mounted rack is probably all you could get to fit one of them, which I assume would also mean getting a tow ball fitted.

As Davidian said, get a new car then not only will you be able to transport bikes, people will also stop mistaking you for a hairdresser.

Another car isn't an option as nowhere to park it.

Not aware of anybody that makes tow bars for Z4's either, ruling out tow hitch mounting.

Bmw do a bike rack for the Z4, but it involves modifying the back of the car, and is pricey.

Seen a couple of similar arrangements by other manufacturers on american cars too, but looking for a better alternative.
